Urbanization, Deforestation, Reforestation
2009 was noted as the first year that more people lived in urban spaces than in rural areas. The hope that a majority urban population would slow the clearing of tropical forests — our most effective carbon sinks — seems, however, to have been misplaced. The idea was simple: if more people moved into forested…

Is Ocean Water Helping to Melt Glaciers?
After crossing the Ross Sea, we’ve reached our first study area: the “Little America Trough.” The oceanographers on board want to find out if warmer water from the deep ocean is rising onto the continental shelf and reaching the ice, making it melt faster. They measure temperature and salinity as well as the water currents.…

A People's Plan of Action to Fight Extreme Poverty
Government leaders cannot solve global challenges on their own any more. In today’s much flatter world, it is everyday people –and, critically, their personal networks–who have the potential to be the world’s big new problem solvers.

High, Dry and Safe: In Search of the Perfect Site
The ideal spot for a seismic station is dry, quiet and safe from vandals and thieves. Seismometers record slight ground motions, allowing them to hear distant (and not so distant) earthquakes. But cars or even kids playing near a seismic station can produce ground vibrations that overwhelm the subtle sounds of earthquakes. Seismic stations include…

Saving water, paying more?
New York City’s Water Board (which determines the finances for Department of Environmental Protection’s water system) is proposing a water rate increase of 14% for fiscal year 2010. According to an article in the Daily News, the rate increase is needed because New Yorkers are using less water, meaning that DEP is earning less revenue.…
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
